HANGER DEVELOPMENT –

PAST TO PRESENT

Over fifty years ago, vibration control hangers were

in their infancy and it was not uncommon to use

isolation materials such as a block of cork with a

hole drilled through the center, two or three layers of

rubber and cork pads or felt within the hanger frame.

These products all gave way to the lower frequency

bonded steel strip rubber-in-shear elements and then

to round rubber-in-shear designs which were lower

in cost and higher in capacity. The next step was

equivalent deflection in compression.

The compression elements were designed with

straight line deflection curves, so that for a given

deflection the frequency would be about the same

as the rubber-in-shear. The advantages were greater

capacity for the same size and a fail safe feature.

The upper steel washer in the rubber element is still

made larger than the hole in the hanger box, so that

if the rubber burns or fails, the piping, equipment, or

suspended ceiling remains captive.

Both the round rubber-in-shear and the round

compression hangers were also merchandised with

a single deflection element in the top and bottom of

the box to provide twice the deflection and lower the

frequency. Our company went on to develop a larger

taller double deflection element capable of providing

this same deflection in one piece.

Up until 1965 we manufactured a complete range of

0.2"(5mm) single deflection hangers. They were in the

same frequency range as fiberglass and very com-

petitive but we found their performance so limited that

we no longer wished to manufacture them although

others still do. The only exception to this is the WHR

which is still offered for ceiling suspension as a fiber-

glass substitute or improvement when fiberglass is

specified by others.

HD Hangers are double deflection units with average

static deflections of 0.4"(10mm). They are molded in

LDS because of its excellent aging characteristics. If

you wish to isolate primary vibration, they should only

be considered for smaller equipment running above

800 RPM in non-critical areas. The principle function

of HD Hangers is noise isolation.

Spring Hangers followed their own evolution. As in the case of mountings, early spring hangers had very stiff, tall, unstable springs and it was not unusual to sell hangers with 0.375"(10mm) deflection. Spring Hangers contained no rubber for high frequencies and the first improvement was the introduction of a rubber washer. This was normally located under the top of the box, or later on against the spring cup on top of the spring. A steel washer over the rubber washer spread the load to the outside of the steel spring so a cheaper steel cup could be used. When the rubber washer was located under the top of the box or over the steel spring, the design was still extremely poor as there was nothing to keep the rubber washer centered on the steel cup. Thus, the steel hanger rod would rub the steel cup or the steel hanger box and short circuit the action of the rubber. This was not recognized as a worry in that era, so the next step was to increase the deflection. Since spring stability was not clearly understood increased deflection was accomplished by making the springs taller, but not necessarily larger in diameter. The springs could not collapse or fall over because the lower hole in the box continued to be conveniently small. When the spring tended to topple, the rod would hit the side of the box and stop. Of course, the rubber continued to be short circuited and often the rods would lock vertically (especially if they were fully threaded) so that the springs were bypassed as well.

We reduced these problems by writing specifications and manufacturing hangers with the hole in the bottom of the hanger box as large as the I.D. of the spring. The HS Spring Hangers evolved using our standard A, B and C Springs and seating them in LDS cups with projecting bushings to line the hole in the lower end of the box. A, B and C Springs are designed for horizontal stiffness as described on Page 1, 4, 5 and 8 of Bulletin SLF-200, so they do not fall over or buckle. Centering the spring in the acoustical cup made steel-to-steel contact of the rod and the top steel cup unimportant and put the rubber in the right location on the leaving end of the spring.

The Series 30 was designed in recognition of a consultant’s field criticism that he was tired of walking job sites and seeing the hanger rods rubbing on the rubber bushings. This happened because standard hangers allow for only limited rod angularity. The only way to solve the problem was to design a whole new series of springs which would be larger in diameter and shorter. To the best of our knowledge this was the first time that a group of hangers were designed to provide a specific angular capability. The designation 30 means the rod can swing through an arc of 30 degrees from side to side in any direction before contacting the rubber bushing. The photographs show HS and series 30 hangers. The difference in the proportion of the springs and the angular capability is quite apparent. Spring hangers provide good vibration isolation where there is very little high frequency noise. They are generally recommended for applications like ductwork suspension or for suspending pipe lines where twin-sphere rubber connectors were used to take out the high frequencies first.

The Series 30 design solved the short circuiting problem, but we were still dealing with a design having poor high frequency control. The elastomeric cup is a much improved washer that cannot short circuit, but still a washer. The idea of placing a steel spring in series with a rubber hanger element started about 1957. Our DNHS Series was the first improvement on early designs, and the 30N configuration was the obvious advance on the DNHS as they incorporate the 30 degree swing capacity. Series 30N are the top-of-the-line and recommended for all highly critical locations where it is equally important to isolate both noise and vibration.

HS and DNHS designs using our standard A, B, C and multiple C designs are nominal 1"(25mm) and 1.35"(34mm) deflection hangers respectively. The Series 30 and 30N are grouped out with similar deflections, but then go on to our Series 30N-100 utilizing the 2"(50mm), 3"(76mm), 4"(102mm) and 5"(127mm) deflection springs used in the SLF-100 Mountings. The 3"(76mm) & 4"(102mm) Series 30N-1000 were introduced to satisfy lighter capacity needs. The newer B2 and C2 designs are nominal 2"(50mm) and 2.35"(60mm) deflection hangers meeting lower cost competitive criteria.

HANGER DEVELOPMENT

Series 30N Hanger

While most problems are addressed by the hangers listed above, we had need for one more variation. This is a precompressed PCHS, PCDNHS, PC-30 or PC-30N. When these hangers are released, they have the same vibration isolation characteristics as the standard versions. They have the advantage, however, of being preloaded in our shop by means of the washer and adjustment nut on the bottom. The spring deflection is shown on a scale inside the box so you know both the rated load and the deflection. A precompressed 1000 pound hanger acts as a rigid connection during installation unless the load exceeds the 1000 pounds(454kgs). Therefore, the installation may proceed in much the same manner as one with solid rods. This is particularly important when installing large diameter (6"(152mm) and over) pipe where the changes in elevation that would occur with ordinary spring hangers have forced contractors to install the piping systems solidly and then cut the rods and install the spring hangers later.

When the PC designs are used the whole run is completed and then the nuts below the lower washer are released to allow the spring to act freely. Any minor errors in load assignment results in negligible elevation changes and any major error would be noticed on the deflection scale and corrected by adjustment. In addition to installations as described above these hangers are recommended for the first three suspension points near the equipment so loads can be accurately determined to eliminate the effects of the piping weight and stress on the equipment flanges. They are recommended for seismic applications where the precompression washers act as upward limit stops when cable restraints are used. Hanger housings must be strong enough to accept the compressive force and transfer it to the 1/4" rebound washer on top.

With the exception of a few very low capacity hangers and welded high-capacity and multiple-spring designs all of our hanger boxes are made by bending steel flats into an inverted U shape with return bends on the bottom, and arc welding them to thick American Standard or special steel washers. We believe that this construction is far better in appearance and safer than the more common spot welded, overlapped sheet metal designs favored by our competitors. That is why we continue to use this more expensive construction.

This heavy box construction serves another purpose in seismic zones. When an earthquake occurs, the spring allows vertical pipe motion. Wherever cable cross bracing is used, the piping tends to swing upward as well. In order to control this motion, we use the “RW” design. “RW” stands for Rebound Washer. It is an oversized molded assembly with 1/4"(6mm) LDS Rubber bonded to a steel washer that is set 1/4"(6mm) below the bottom. As motion becomes excessive, it pushes the box upward. The upward motion is cushioned by a 1/4"(6mm) rebound washer between the hanger and the overhead. See page 5 for a typical installation. The hanger box must have the strength to withstand major forces. Our schedules call out the vertical G ratings. The competition doesn’t bother.

On the bottom of this page, we illustrate “W” hangers originally designed for suspending ceilings by means of wire. Many ceilings are supported by bolted arrangements, but we have continued with the “W” designation. For information on these hangers, please refer to Bulletin CH-620 in our Architectural section.

HES Hangers are installed at riser suspension points to control load shifts as the riser expands or contracts. If a 120 foot(37m) steel riser goes through a temperature increase of 150°F(66°C), the piping will expand 1.4"(36mm). If the piping had an anchor point in the basement, the piping bracket at the 60’(18m) elevation and the top bracket would rise 0.7"(18mm) and 1.4"(36mm), respectively. This travel would transfer the entire piping weight to the basement as the piping would lift off non-resilient support points. Standard 1"(25mm) deflection hangers would lose 70% of their load at the 60 foot(18m) point and the complete load at the top of the run. Therefore, HES Hangers are needed because of their higher initial deflection and travel capability. If HES Hangers with 4"(102mm) initial deflection were selected, the hanger at the top would lose only 35% of its load and the intermediate hanger only 18%. This would substantially reduce the load shift to the basement anchor.

Special larger deflection hangers would be even more effective. In handling this type of problem, it is preferable to anchor the riser at the center of the run. If this had been done in the piping problem described above, each end would have expanded outward only 0.7"(18mm) instead of the 1.4"(36mm). The upper hangers would have lost 18% of their load since the springs would be unloaded the 0.7(18mm) of an inch.

The springs in the hangers on the lower end of the piping would have been compressed 0.7(18mm) of an inch thereby increasing their load by 18%. With this loss and gain situation, the piping always remains balanced at the neutral point.

EXAMPLE–

6"(152mm) Schedule 40 piping weighing 36 pound per foot(4.94kg/m) with water. The run of 120 feet(37m) would weight a total of 4320 pounds (1960 kgs). If the piping is anchored at the center we might select support points at the lower end, the 30 foot(9m) and 90 foot(27m) marks and at the top. Therefore, we would have 4 locations or a total of 8 hangers supporting 504 pounds(229kg) each. The preliminary selection would be 8 HESB-750 Hangers. The initial hanger deflection would be 540 pounds(245kg) divided by the spring constant of 167 pound/inch(2.98 kg/mm) which equals 3.23"(82mm). The total spring deflection would be the initial deflection plus the expansion travel or 3.23"(82mm) plus 0.7"(18mm) which equals 3.93"(100mm). The hanger must then be checked to see if this deflection is within the range of the selected hanger. Since the HES Hangers can over travel the rated deflection by 40% the HESB-750 can travel 4.50(114mm) X 1.4(36mm) or 6.30"(160mm). Therefore, the selection is correct. If this number were smaller than the required 3.93(100mm) it would be necessary to use the next larger hanger and check again. (Actually this hanger needed no checking as the 4.50"(114mm) rated deflection already met the conditions).
